HCL + Hydrogen Peroxide etchant solution slow
2004-11-11 by gmc_za
I have made a solution of 1 part HCL (30%), 1 part Hydrogen Peroxide (30%) and 2 parts H2O (I've also tried 1 part H20) and my board takes about 30-45 mins to etch. By this time some of the wanted tracks are eaten away. From what Ive read it should taken minutes. What am I doing wrong? 1) Maybe I dont have enough volume of the stuff - How much etchant is needed for say a 10x10cm board 2) Are my parts Hcl:HydrogenPer:H2O correct? Thanks. Greg
